Eaton DH323NGK - 100A, 240V, 3-Pole, Fused Disconnect Switch

The Eaton DH323NGK is a high-performance fused disconnect switch engineered for dependable electrical isolation in demanding industrial and commercial settings. With a 100A rating at 240V and a three-pole design, it delivers clean, reliable disconnection under load while seamlessly supporting lockout/tagout procedures to keep workers safe during maintenance and service.

Three-pole configuration ensures complete isolation of all phases in three-phase systems, making it ideal for motors, conveyors, pumps, and HVAC equipment. The built-in fuse mechanism provides rapid interruption of fault currents, protecting downstream components and reducing the risk of damage during faults or startup transients. The NEMA 1 enclosure offers sturdy indoor protection, making it a practical addition to control panels, equipment rooms, and industrial enclosures where cleanliness and reliability matter.
